Hi I program business logik in ERP systems in Visual Studio with vb.net and C#. Now I would like to try and learn to make app's so maybe one day and I can make app's that show business data. But beeing new to this I find it difficult to get started. There is a lot of new words I don't know the meaning of and it is difficult to find out how to best start making app's. I started looking at Xamarin beeing used to VS and all, but I just found out that this seems to be obsolete? I would like to only write code once and use it on both android and ios - but is this realistic? So... Any recommendations where to start? A good place be be guided through which buzz words I need to know about and the technology they represent? Should I use Xamarin, or Flutter or...??? Hands on example that makes it easy to learn by doing? Any recommendations will be appreciated :-) Another old dog that wants to learn new tricks :-)
